Frank Edgley does respond at edgleyconcertinas@gmail.com he sent me a price list a few days ago.
His web site has two email addresses listed and price list has yet another, this may be an oversight on his part.
I know he is away for a few days. But he does respond.
His heritage model starts around 4,399.00 USD plus options. You're best to contact him directly. He has many options.
